The ASM 3660DD4 gives the users real time information about Ride-Thru System functions, and can be used to monitor and present power quality issues that can cause process disturbances and production loss. A history of power quality events is stored in persistent memory for later analysis, showing the effectiveness of the Ride-Thru System. The ASM 3660DD4 Ride-Thru Monitoring System is designed to monitor and display information about the Bonitron Ride-Thru System, such as the present values of the system voltages and currents, or any fault conditions that may exist.
